Agreed with Genesect being A+. U-Turn spam and its special movepool is quite great. Specially based mixed set is definitely a threat that can both do damage and pivot out. Not to mention the huge boost it gets from Download.

While Hoopa-Unbound is not an S tier Pokemon, I see it at A+ due to its spammability and the fact that it has no counters. Nothing can risk switching to it, even the best walls or some Pokemon that resists its STABs like Mega Mawile since most, if not all, of them can be OHKOed or 2HKOed by Life Orb set. It absolutely destroys stall, including Chansey due to Psyshock + Nasty Plot. Also, fun fact : it actually beats Ash-Greninja and Tyranitar, even AV set which is hardly used.

252 SpA Life Orb Hoopa-Unbound Focus Blast vs. 248 HP / 252+ SpD Assault Vest Tyranitar: 400-473 (99.2 - 117.3%) -- 93.8% chance to OHKO

252 SpA Life Orb Greninja Hydro Pump vs. 0 HP / 0 SpD Hoopa-Unbound: 160-188 (53.1 - 62.4%) -- guaranteed 2HKO

252 SpA Life Orb Hoopa-Unbound Focus Blast vs. 0 HP / 0- SpD Greninja: 614-723 (215.4 - 253.6%) -- guaranteed OHKO

Since Hoopa-Unbound is here, Hydreigon is prepared for a huge drop since its real niche now are only defensive typing, Levitate and ability to pivot using U-Turn. However, it is power-creeped by Hoopa-U by a huge margin. Even though its speed is higher, Ash-Greninja does it better in this department as a Dark type special attacker (which I forgot to rank up).
